Filed Nov. 26, 1929 /7 "l'lTann Patented May 17, 1932 UNITED STATES LEWIS H. ZANE, OF MAUGH GHUNK, PENNSYLVANIA smoxn AND SPARK ELIMINAT'OR Application filed November 26,1929. Serial No. 409,896.

The present invention relates to smoke and spark eliminators adapted for mounting on smoke stacks, particularly the smoke stacks of locomotives or the like.

An object of this invention is to provide a device for this character which will prevent sparks or the like from being projected by the smoke stack.

Another obj ect of this invention is to provide a device of this character which may be readily mounted on any smoke stack without altering the present structure and which may be controlled at apoint remote therefrom.

A further object of this invention is to provide a device of this character which will eliminate the objectionable smoke which is being emitted from the smoke stack when the engine is in the shed or the like where particular objection is made to excessive smoke being emitted by the engine.

The above and various other objects and advantages of this invention will in part'be described in and in part understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawings wherein Fig. 1 is a fragmentary detail side elevation of a device constructed according to the preferred embodiment of the invention;

Fig. 2 is a top plan view of the device; and

Fig. 3 is a sectional view partly in elevation taken substantially on the lines 33 of Fig. 2.

Referring to the drawings wherein like numerals of reference designate corresponding parts throughout the several views, the numeral 10 designates generally a boiler which may be a component part of an engine or the like and which is provided with an upstanding smoke stack 11 of conventional construction. The boiler 10 is preferably provided with a cab or control room 12 adjacent the rear thereof.

A smoke and spark eliminator 13 which is preferably of tubular construction and substantially ring shaped is mounted on the smoke stack adjacent the top thereof. The smoke eliminator 13 is preferably secured to the stack by a resilient clamping ring 14 having outstanding spaced arms or lugs 15.- The arms 15 are provided with apertures 16 through which a securing bolt 17 is mounted.

The clamping ring l iis provided with upstanding apertured lugs 18 which register with complementary apertured depending lugs19 mounted on the ring 13 and are secured together by bolts or rivets2O or the like.

The ring or smokeeliminator 13 is preferably provided with a plurality of spacedly positioned apertures 24 which are positioned 'on the ring adjacent the upper inner end portion thereof, so that when the steam or air is emitted from the openings the steam or air'will be emitted in the form of a coneshaped column, the apex of'which'extends spacedupwardly from the top of the stack 'so that any-smoke or cinders rising from the stack must pass through the steam cone which will dampen the sparks and the smoke.

A conduit 21 is secured at one end to the ring- 13as at 22 and at the opposite end is connected to a suitable steam line, and is provided with a control valve 23 which is interposed in the conduit 21 and positioned at a point remote therefrom preferably in the cab or control room 12 so that when the valve 23 is opened, the desired quantity of steam will pass through the conduit 21 and into the" eliminator 13.

In the operation of this device, the valve 23 may be opened when the engine is being fired and a quantity of smoke or cinders is being emitted from the smoke stack 11 thus permitting the steam to pass outwardly through the conduit 18 into the ring 13. The steam or air entering the ring 13 will pass outwardly through the openings 24: being ejected upwardly in the form of a cone which will substantially blanket the top of the smoke stack so that any smoke or cinders being emitted from the smoke stack will be required to pass through the steam screen thus formed.

It will therefore be obvious that the steam screen will dampen the cinders or sparks and be co-mingled with the smoke sufficiently to dampen the smoke and prevent the same from passing upwardly, while at the same time assisting in forcing the draft of air through the smoke stack.

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of the invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is A smoke and spark eliminator comprising an annular tubular member, adjustable clamping means for mounting said. annular.

member in spaced relation to and about the periphery of a smoke stack, said annular member when in mounted position being substantially below the top of the smoke stack, connecting means connecting the tubular member with a steam line, said clamping means comprising a split ring and upstanding lugs secured to said ring, said tubular member having depending lug members adapted for engagement with said upstand-' ing lugs of said ring, and means for securing the lugs of said tubular member and said ring together, said tubular member having a plurality of spaced openings adjacent the upper portion thereof, said openings being inclined in converging relation to each other whereby to project a conical column of steam over the top of the smoke stack, the apex of said column of steam being positioned ata point spaced upwardly from the top of the stack. 7

In testimony whereof I hereunto afiix my signature.
